I'm trying to help a buddy out for this Friday race night. For the summer season we are just running USGT 21.5. The issue is he has a 2013 BD7 and we cant get the gearing to work. Wondered if there is a different motor mount set up? We went to smaller spur gear to allow for a bigger pinion. But the support just in front of the motor mount is in the way. Suggestions please. or does he have to buy a 2015?

You can try to grind away a bit off of the mount support with a dremel. What gearing are you trying to hit and with what spur/pinion combo?

For 21.5 gearing, maybe a 48 pitch combo would be cheaper to do than changing kits. :-)

U r going to have to change the motor mount...I don't know Where u r on gearing..but if u want 4.0-3.5 use a 92-88 spur an u should be fine!!!

I just checked with an old 2013 motor mount I had floating around,
best I could get with what I had was 88T spur and 55T pinion, it just fit.
This will get him down to 3.2

This was without any grinding of the motor mount to get some more pinion clearance, so with a little massaging there is probably a few more teeth you could fit.
A 14/15 motor mount with greater clearance will not install on a 13 chassis.
